IRS-Enabled Backscattering in a Downlink Non-Orthogonal Multiple Access System
Azar Hakimi, Shayan Zargari, Chintha Tellambura +1
Intelligent reflecting surface (IRS)-enabled backscatter communications can be enabled by an access point (AP) that splits its transmit signal into modulated and unmodulated parts.…
Multiuser MISO PS-SWIPT Systems: Active or Passive RIS?
Shayan Zargari, Azar Hakimi, Chintha Tellambura +1
Reconfigurable intelligent surface (RIS)-based communication networks promise to improve channel capacity and energy efficiency. However, the promised capacity gains could be negli…
Energy-Efficient Hybrid Offloading for Backscatter-Assisted Wirelessly Powered MEC with Reconfigurable Intelligent Surfaces
S. Zargari, C. Tellambura, S. Herath
We investigate a wireless power transfer (WPT)-based backscatter-mobile edge computing (MEC) network with a {reconfigurable intelligent surface (RIS)}.In this network, wireless dev…
